Disappearing cresc/dim markings
I click on a note in my score, move the cursor to the palette, double click on a < or a >, and it appears near the note I clicked--OK so far. But then when I double click on the < or > and move it around with the keyboard arrows, as soon as I try to release it by clicking on an empty space in the score it disappears.
Usually it will reappear if I either hit the back arrow or click on the same note again, but either it will 1) reappear in black but won't allow me to edit it at all (i.e. nothing happens when I click or double click on it again except the cursor flash you get when you're clicking on nothing) or 2) it will reappear in blue and allow me to move it and/or change the length, after which it may or may not disappear again. I already hate putting in detailed dynamic indications, and this is making it all that much more time-consuming. Am I doing something wrong? Thanks.
